3 Claims.

My invention relates'to boxes and has for its object to provide a box inwhich commodities may be firmly packed without causing bulging of thesides of the box.

A feature of the invention resides in providing a box which may beconstructed of paper board or similar material and which is particularlyadaptable for use in stripping butterand similar commodities.

Another object of the invention resides in providing a box which isconsiderably less expensive than the ordinary wooden tubs now used forthe purpose of shipping butter.

A still further object of the invention resides in providing a boxhaving a body portion formed with a number of sides greater than fourand having a top and bottom attached thereto.

An object of the invention resides in constructing the body of the boxin one piece folded along .parallel lines to cause the sides of the boxto form obtuse angles with respect to one another.

Another object of the invention resides in constructing the box of acorrugated board arranged so that the corrugations thereof extend acrossthe folds of the walls of the box.

v A still further object of the invention resides in constructing thecorrugated board with a corrugated member having sheets of paperattached thereto and arranged so that the grain of said 0 sheets extendsat right angles to the direction of extent of the corrugations of theboard.

A feature of the invention resides in arranging the corrugations of theboard in a manner to'extend parallel with the upper and lower edges ofthe walls of the box and at right angles to the folds of the bodyportion.

An object of the invention resides in forming the box open at one endand in providing a arranging said sheets in overlying position to form acomposite structure completely closing the open end of the box. I

A still further object of the invention resides in bending flangesoutwardly from the ends of said sheets adapted to lie along the walls ofthe box to effect a closure therebetween.

Another object of the invention resides in providing a closure for thebox consisting of two sheets of material conforming in configuration tothe open end of the box and secured together inwardly from the edgesthereof.

A feature of the invention resides in constructing the box with flangesbent inwardly from the walls thereof and adapted to lie between thesheets forming said closure.

A still further object of the invention resides in scoring the outersheet of the closure along lines parallel to the free edges of alternatewalls of the box and forming tabs adapted to be folded back to permit ofthe insertion of the corresponding flanges of said walls between the twosheets of the closure. 1 2

An object of the invention resides. in construct ing theintermediate'flanges of' the'body of the box with notches adaptedtoreceive the comers of the flaps when in foldedposition and to permit ofthe folding of said flanges in between the walls of the box.

Other objects of the invention reside in the] novel combination andarrangement of parts and in the details of construction hereinafterillustrated and/or described.

In the packing and shipping of butter in bulk conand other similararticles, it has heretofore been impractical to employ pa r boxes due tothe fact that the walls thereof bulge and the boxes quickly lose theirshape and fail to function in a manner to protect the bulk butterdisposed within the same. The present invention provides a box which maybe constructed of ordinary materials such as corrugated paper board andthe like by -means of which butter may be safely shipped and in whichthe walls of the box will not bulge or break during shipment.

In the carrying out of my invention I have found that a box having anumber of sidesin excess of four and preferably eight sides can beconstructed as brought out so as to be sufllciently strong to withstandthe misuse to which it is subjected in the shipment of the same.

For the purpose of illustrating my invention, I have shown in Fig. -1 abox 10 which consists of a body portion 11 constructed of a single sheetof material and open at the top and bottom. This sheet is scored alongparallel lines 12 to divide the box into eight juxtaposed sides or walls13, 14, 15, 16, 17, l8, l9 and 20. The two end walls 13 and 20 may besecured together through a tape 21 which is pasted to the edges thereofwhereby a perimetric body portion is formed which is adapted to befolded into a compact flat form or to be moved into-extended positionfor use.

, The body 10 is constructed of a corrugated board and its constructionis shown in detail in Fig. 3. The board from which the body of the boxis constructed, is indicated at 22 and consists of a corrugated member23 having two sheets of material 24 and 25 glued or pasted thereto. Inthe construction of the board 22 the grain of the two sheets 24 and 25is caused to run at right angles to the direction of extent of thecorrugations 26 of the corrugated member 23. The board 22 is so arrangedin the construction of the box that the corrugations 26 extendperimetrically about the body portion of the box and across the variouscorners of the box formed through the score lines 12 thereon. When thebox is constructed in this manner the span of the various walls of thebox is greatly reduced and the corrugations 26 of the corrugated boardbecome so arranged as to greatly stiffen the walls and provide anextremely rigid structure. By running the grain of the two sheets 24 and25 in the opposite direction, considerable rigidity is also given theboard lengthwise, though the greatest rigidity is had in a cross-wisedirection. Although corrugated board has heretofore been used in boxesthe corrugations have always been run in a manner to reinforce the boxin the direction of its greatest length. In the use of corrugatedmembersI arrange the corrugations in exactly the opposite manner .and inaddition to forming the walls of the box of narrow width, run thecorrugations so-as to reinforce the walls of the box in the direction oftheir shortest dimensions rather than in the direction of their greatestdimensions as has heretofore been the customary practice.

In Fig. 1 I have shown a bottom 27 and a closure 28 for the box. Thebottom 2'7 is constructed of any suitable material andmay be constructedof corrugated board such as used for the body portion of the box andindicated at 22. This bottom is octagonal in form to conform to theshape of the box and is constructed at. its edges with inwardlyextending flanges 29 which are bent from the bottom proper and which areadapted to lie along the lower ends of the various walls of the box andupon the inner surface thereof.

In the erection of the box the body portion 11, which comes folded flat,is placed over a truncate octagonal pyramid 30 as shown in Fig. 9 whichcauses the body of the box to assume its ultimate form. Thereafter thebottom 2'? may be applied to the open end of the box and forced into thesame until said bottom rests upon the truncate surface 31 of the pyramid30. Thereafter the box is removed and the bottom pushed clear down intothe lower end of the box where the flanges 29 of the bottom may beattached to the various walls of the box through staples 32 or in anyother suitable manner. The cover 28 used in closing the box isconstructed similar to the bottom 27 and is formed with flanges 33adapted to overlie the outer surface of the various walls of the bodyportion proper. Theseflanges may be secured together along the cornersthrough strips of tape 34 or in any other suitable manner. I

When the box is to be used for the packing of butter the interior isfirst sprayed with a coating of paraffin and a liner consisting of asheet of waxed or similarly prepared paper is then placed upon theinterior of the box to line the same. Such paper is of a length slightlygreater than the height of the box. In application the paper is firstmoistened and thereafter applied to the interior of the box, the upperedge being turned over the free edge of the box; Through the moisture inthe paper the liner adheres to the box proper and is easily caused tofit snugly upon the interior of the same, the lower edge being turnedinwardly upon the bottom of the box. An end sheet is then placed uponthe bottom of the box and overlying the inwardly turned end of theliner. Due to the fact that the box-is constructed with obtuse angles,the liner may be easily applied within the box and brought into thecorners of the same. Thereafter the butter or other commodity to bepacked in the box is placed therein and the upper surface leveled off byrunning a scraper over the upper edge of the box. The folded over up.-per edge of the liner is next turned inwardly and an upper end sheet ofsimilar material placed upon the end of the butter. The cover 28 maythen be applied to the box. If desired, strips of tape, indicated at 35and 36 may be run about the joints formed between the cover and bottomof the box and the body portion thereof to completely seal the box andprotect the contents of the same.

In the form of the invention shown in Figs. 4 and 5 a different type ofclosure has been illustrated which consists of four strips or sheets ofstock 37, 38, 39 and 40 which are each of a width equal to the width ofone of the walls l3, 14 etc. These strips are of a length somewhatgreater than the distance between opposite walls of the box and aredisposed one uponthe other in overlapping position and secured togetherthrough staples 41 or in any other suitable manner. The

' various sheets 37, 38, 39 and 40 are scored near their ends asdesignated at 42 and 43 to form flanges 44 and 45 which are adapted tobe bent outwardly from the body of the closure and to fit along thevarious walls of the body of the box previously referred to. The scorelines 42 and 43 may be located so as to bring the flanges Y44 and 45within the interior of the box as shown in Fig. 4 or the same may beconstructed so that and the entire box may be made with ordinarymachinery and without any die cutting whatsoever, thereby greatlyreducing the initial expense in the manufacture of the box. The bottomfor the box-shown in Fig. 5 is applied to the box in identically thesame manner as the bottom 27. If desired, however, the closure may beinverted as designated at 46, whereby the same may be attached to thebody proper through staples 47 which pass through the various flanges inthe closure and the box proper. When the box is so constructed, theparts may be applied after the contents of the box have ben inserted. InFigs. 6, '7 and 8 still another form of my invention is shown in which adiflerent type of closure is employed. In this form of the invention thewalls of the box are constructed the same as in the other form of theinvention and are designated by the reference numerals 48 and 49. Thereare eight of these walls and the said walls are constructed at the topand bottom with flanges 50 and 51 which are folded inwardly from saidwalls as clearly shown in Fig. '1. In conjunction with both the top andbottom of the box, a closure, such as shown in Fig. 8 is employed. Thisclosure consists of two sheets of material 52 and 53 which are securedtogether through staples 54 or in any other desired manner. The staples54 are located considerably inwardly from the box to leave the marginalportions thereof free. Along four of the edges of the sheet 53 areformed four score lines 55 which are disposed inwardly from said edges adistance somewhat greater than the width of the various flanges 50and.51. These score lines form flaps 56 on the closure which are adaptedto be bent outwardly as shown in Fig. 8 to permit of the insertion ofthe various flanges 51 therebetween. It will'be noted that only fourscore lines 55 are provided forming four flaps 56 which receive the fourflanges 51 formed on the body portion. It will be further noted thatcomers 58 are provided at the intersections of the score lines 55 andthe flanges 50 are formed with notches 59 which receive said corners andpermit of insertion of the said flanges in between the flaps 56. whenthe two adjoining fiapsare simultaneously folded outwardly. By means ofthis construction four flaps are provided which are easier to handlethan eightfiaps and which do not'weak'en the closure as much as theeight flaps and which at the sametime swing outwardly in a convenientmanner to re- .ceive the various flanges of the box body proper.

If desired the sheet 52 may be formed with flanges 60 along the edgesthereof which extend outwardly from the closure and which are adapted tolie along the inner surfaces of the walls of the box.

In the application of the closure shown in Fig. 8 to the box'shown inFig. 7." one of the flaps 56 is bent outwardly and the correspondingflange 51 of the box proper inserted into the same. Thereaitertheadjoining flap is folded outwardly and the two corresponding flangesassociated therewith inserted in between the two sheets of material.This procedure is repeated until all of the flanges of the body of thebox have been received within the space provided betweenthe two sheetsof material. Thereafter the joint between the closure and body may besealed through adhesive tape or in any other suitable manner.

My invention is highly advantageous in that an extremely rugged andsubstantial box is formed in which various commodities, such as butterand the-like, may be packed and shipped without injury to. the contentsof the box. The liner employed with the box is readily inserted 'in thesame and requires little or no inconvenience in the causing of the sameto fit snugly about the inner walls of the box. The box can beconstructed of ordinary materials such as are now available for thepurpose and the materials are so utilized as to bring about the mosteflective results. The closures for the box can be readily applied tothe same and through the use of the erecting block provided, can bequickly and easily erected. With the-invention the entire contents canbe sealed through the use of adhesive tape or in any other suitablemanner so as to completely protect the commodity contained within thebox. The invention is highly meritorious in that the box can beconstructed at a fraction of the cost of wooden tubs heretofore used forsimsheets of material conforming in configuration to, the open end ofthe box and overlying one an-' said flanges are folded into positionbetween the sheets of the closure.

2. In combination with a box open at one'end and having an even numberof juxtaposed walls,

greater than four, each forming an obtuse angle with respect to theadjacent wall, a closure for said box comprising two sheets of materialconforming in configuration to the open end of the box and overlying oneanother, means for securing said sheets together inwardly of the edgesthereof, flanges formed on the ends of said walls and bent inwardly tofit between the sheets forming said closure, the outer of said sheetsbeing scored along a number of lines equal to one-half the number ofwalls of the box and parallel with some of said walls, said linesforming flaps adapted' to be turned back to receive the correspondingflanges of the box and converging at localities opposite the otherflanges of the box, the flanges of the box opposite the converging endsof the score lines being notched to clear the corners formed by theadjoining fiaps while said flaps are folded tbaclrto receive saidflanges,

3. In combination with a box open at one end and having eight juxtaposedwalls, each forming an obtuse angle with respect to one another, aclosure for said box comprising two sheets of material conforming inconfiguration to the open end of the box and overlying one another,means for securing said sheets together inwardly of the corners betweensaid flaps overlying portions of some of said flanges, said last namedflanges being notched to clear the corners formed between adjoiningflaps while said flanges are folded into position between the sheets ofthe closure.
